Time for a new WIP:
http://dehacked.2y.net/microstorage.php/info/1373094116/MUGG-KAM%20v3%2C100.vbm
(I missed a treasure chest in room 10 of the ice world, so I'll need to redo the last part of the run)
I found some new tricks:
Faster way of climbing ladders
Pressing 6 frames upwards than 1 frame sidewards is the fastest way to climb ladders. (Somehow, however, pressing upwards 3 frames instead of 6 apparently has the same effect)
Keeping momentum when bumping against walls
Press the opposite direction right before bumping against a wall. Directly landing on the floor without any bumping is better, though. So it's only good to use it when there's no other way.
No momentum during starting-animation of wheel
Sorry, I'll have to do some research on this, but you can see an example of it in the WIP at frame ~16500.
